What Brooklyn faces
Each hazard’s share of the building damage FEMA expects here, and how its rate compares with the rest of the country.
River and rain flooding
Tornadoes
Hail
Shares are of FEMA’s expected building damage, the measure the grade uses; ranks compare each hazard’s building-damage rate with all 85,154 U.S. census tracts. In FEMA’s terms, river and rain flooding is FEMA’s “Inland Flooding” (rivers and streams overflowing their banks, or rain overwhelming drainage). FEMA defines coastal flooding as high or rising tides and storm surge, so surge damage is counted there. Drought isn’t listed: FEMA counts its losses in crops only.
What’s behind Brooklyn’s grade
River and rain flooding is 70% of the building damage FEMA expects in Brooklyn, and Brooklyn’s rate of river and rain flooding damage is lower than 54% of U.S. census tracts. Hail adds 13%, at a rate in the top 8% of U.S. census tracts.
B lower expected damage per building than 63% of U.S. towns (21,298).
All of Brooklyn’s residents live in one census tract; the figures are that tract’s.
In dollars, FEMA expects about $558K a year in losses across Brooklyn: $322K to buildings, the rest to people and crops.
Does Brooklyn flood? No paid flood claims on record
FEMA’s records show no paid flood insurance claims in Brooklyn. That’s not a promise: most homes don’t carry flood insurance, so small floods go unrecorded.
Brooklyn isn’t in FEMA’s Community Rating System, which cuts flood insurance up to 45% in towns that do extra flood-proofing.
Insurance rates: Green County.The storms Brooklyn remembers
None of the 14 disasters declared for Green County shows FEMA aid or repair money reaching Brooklyn itself in FEMA’s records, so these are its biggest flood-claim years.
Green County has had 14 natural disasters declared by the President since 1953, most often severe storms, then winter storms. Not counted: the 2005 Hurricane Katrina evacuee emergency, which covered counties that took in evacuees.
